MONTPELIER — Gov. Peter Shumlin said Saturday that weekend rainfall has elevated the risk of flooding across the state, and he urged Vermonters to pay attention to weather reports and keep an eye on local waterways where flooding was possible.

The governor said Vermont transportation and emergency management agencies were prepared for a weekend response, and the Vermont State Emergency Operations Center will remain open as long as needed.

“I spent part of Friday surveying damage from flash flooding that hit areas of Chittenden County hardest, but now our threat is sustained rainfall that could cause more widespread flooding in others areas of Vermont,” Shumlin said in a statement. He said Vermonters should drive with caution and avoid water-covered roadways, and keep an eye on local rivers and streams as the rainfall continues.

The National Weather Service posted a flood watch Saturday in most of northern Vermont and a flood warning in Caledonia County. A flood warning was also in effect in St. Johnsbury and Lyndonville, but not limited to those areas. Water was expected to approach low-lying areas of Routes 5, 114, 122 and Stevens loop Road north of Lyndonville, the weather service said.

The weather service said moderate to heavy rainfall would continue through Saturday night, and storm total rainfall amounts of 1 to 3 inches can be expected by today.

In the Stowe-Morrisville area, forecasters said snow accumulations of 1 to 2 inches were possible, and said there could be isolated power outages due to wet, heavy snow. Green Mountain Power reported more than 1,700 outages Saturday afternoon.

Campers and hikers were warned to prepare for winter-like conditions in the mountains this weekend.
